T0 @ZZ whom, t may concern..-

Be it known that I, JOHN L. OLARK,a citizen of the United States,residing at Rockford, in the county of Winnebago and State of Illinois,have invented certain new and useful Improvements in 'Flue-Stoppers, ofwhich the following` is a specification.

The object of this invention is to construct a line-stopper in which twobows are pivotally connected to the plate of the stopper in a manner tofold, so that they may be closely packed.

In the accompanying drawings, Figure 1 is an isometrical representationof myimproved flue-stopper with the bows extended. Fig. 2 is a similarrepresentation, in which the bows are folded; and Fig. 8 is a view ofthe outer face of the plate of the stopper, showing the clamps holding.the bows in connection with the plate. Fig. 4 is a section of the baseand center plate, showing their connection.

The plate l of the stopper is of circular form and may be ornamented inany suitable manner to meet the requirements of the trade. The centerport-ion of the plate has four perforations. A clam ping-plate 2 hasfour semicircular recesses 3, arranged radially from the center of theplate, and has four ears 4, passing through the perforations in theplate of the stopper and clenchedLas shown at Fig. 3. Two bows 5 and 6are of the same size and shape,having their ends locatedin the recesses3 in the clamping-plate, thereby forming a folded into the positionshown at Fig. 2 for shipment, occupying a small space.

I claim as my invention-v 1. In a flue-stopper, the combination of abase-plate, a center plate connected with the base-plate having foursemicircular recesses extending radially from the center of the plate,and two bows having their ends located in the recesses and adapted tocross each other when extended.

2. In a liuc-stopper, the combination of a base-plate, a center plateconnected with the base-plate having four semicircular recessesextending radially from the center of the plate, and two bows havingtheir ends located in the recesses and adapted to cross each other whenextended, their crossing-points formed with notches which engage eachother and hold the bows in their extended position.
